Overview
The ADS1286UC/2K5 is a 12-bit micro-power sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a differential input, an integrated sample-and-hold amplifier, and consumes only 250 μA of supply current. The device supports a maximum sampling rate of 20 kHz and communicates via an SPI and SSI compatible serial interface. It is available in an 8-lead SOIC package with an operating temperature range of -40°C to +85°C.
Feature Summary
- 12-bit resolution with guaranteed no missing codes
- Low supply current consumption of 250 μA
- 20 kHz maximum sampling rate
- SPI and SSI compatible serial interface
Applications
- Remote data acquisition
- Isolated data acquisition
- Transducer interface
- Battery operated systems
Procurement Notes
Verify the ordering suffix /2K5 indicates a tube packaging quantity of 2500 units as specified in the datasheet. Confirm the UC suffix corresponds to the -40°C to +85°C temperature grade and ±1 LSB integral linearity specification. Ensure compatibility with 5V logic levels and power supply requirements before procurement.
Selection Notes
Select this component for applications requiring low power consumption and moderate speed. The 12-bit resolution and 20 kHz sampling rate suit general-purpose data acquisition. Consider the 8-lead SOIC package for surface mount designs. Verify that the system can accommodate the required reference voltage range and serial interface timing constraints.
Part Context
The ADS1286UC/2K5 belongs to the ADS1286 family of 12-bit ADCs from Texas Instruments. The UC variant specifically denotes the SOIC package with extended temperature range (-40°C to +85°C) and tighter linearity specifications compared to other grades like UA or UB. The /2K5 suffix designates the bulk tube packaging format.
Replacement Considerations
Direct replacements within the same family include ADS1286UA/2K5 and ADS1286UB/2K5, which share the same package but differ in temperature range and linearity accuracy. Cross-family replacements may require interface and performance validation.
